OVERVIEW:
Climate change is rapidly altering conditions in the
ocean, and organisms exhibit complex responses to
these changes. For many fish and invertebrates,
changing temperatures are altering their
characteristic spatial and seasonal distributions.
Fisheries provide a two-way connection between
changing ocean environments and local economies. As
the distribution and abundance of species change,
where, when, and how many fish are caught will
change. Fisheries also respond to economic
conditions or management policies, leading to
feedbacks onto fish populations. In order to
understand the impact of warming on fisheries
ecosystems, it is essential to account for dynamical
interactions between populations, fisheries, and
markets. This project will develop an integrated
view of the complex relationships between climate
change, oceanography, ecology, and economics in a
coastal marine setting.
This study will advance our understanding of how
physical changes affect biological patterns, which
then impact fisheries and how ecosystem changes
influence economic incentives that feedback to the
fishery and affect the abundance of fish. The Gulf
of Maine, which includes economically valuable
lobster and groundfish fisheries, provides an ideal
test-bed to understand these dynamic linkages. This
system exhibits strong temperature gradients,
gradual warming, and recent warm events. Gradual
warming has altered the distribution of fish, but
the greatest impacts on the coupled system have come
from acute warm events.
Record warm temperatures during 2012 led to an
earlier shoreward migration of lobsters, making
them easier to catch. Although the lobster catch set
a new record, a collapse in prices due to a market
glut reduced the total landed value. The proposed
multidisciplinary study will examine how warming
events, as well as gradual temperature trends, alter
the dynamics of a complex ecological and economic
system.
